SPECIFICATION forming part of Letters Patent No. 648,821, dated 1,

. Application filed September 8,1899. Serial No. 729,832. No modelh To0.5L 071 0111, it may concerni- Be it known that I, HARRY ROBERT VHITE,of-Hartford, in the county of Hartford and State of Connecticut, haveinvented a new and Improved Lubricant-Feed, of which the tion.

The object of the invention is to provide a new and improvedlubricant-feed, more especially designed for use on locomotive-enginesand other engines and machines and arranged to automatically feedmeasured quantities of the lubricant at regular intervals to the steam-The invention consis'tsof novlfat u res an' parts and combinations ofthe same, as wi 1 A practical embodimentof my invention is representedin the accompanying drawings, forming a part of this specification, inwhich similar characters of reference indicate corre sponding parts inall the views. v

v Figure 1 is a side elevation of the improvement as applied to alocomotive-engine. Fig. 2 isan enlarged transverse section of theimprovement on the line 2 2 inFig. 1. Fig 3 is a similar View of thesame with parts in a different positiornand Fig. vtis a sectional planview of the carrier-valve on the line 4 4 body A in the form-of a plug,and,.as shown in Fig. 1, is attached to steam-chest B, an oilpipe 0discharging oil and steam under pressure into a'receiving-chamber D,formed in the bodyA, it being undcrstoodthat the oil-' pipe is alsoconnected with the usual oil and steam supply located in the cab of 'theloco motive and of the usual construction. "'--'.l"he..

the lower end of a cylinder E, formedinfthe body A, -and closed at thetopbyfa-capAQ.- forming part of the body A; In the cylinder E is mountedto reciprocate a piston F, nor mally in a lowermost position andadapted. to be forced upward .by the steam entering thereceiving-chamber D audpressing against the under side of the piston, sothat the lat-' ter moves to the position shown in Fig. 3.

ends of. the cylinder E are connected hyaport (1 in the side wallofthecylinder to .allow thesteain to pass from the lower end of .thecylinder by way of the port 1.! into the upper end of the cylinder toexert erj ualizingpressure on the top t-hereof,'so that the pisa andopens a branch port Z1, leading fromthe inside of the cylinder tothe'port (1 directly above the piston when the latter is in a low ermost position, asshown inl 'ig. 2.

" Now the steam is cut off from the'up'periend of the c; illld6lE,3,uuthat portion of the steam entrapped in this end of thecylinderg'radually condenses, and as soon as this has taken place thepressure of the steam in the receiving-chamber and the lower end of thecylinder is again sufficient to move the piston l" to its previousposition (shown in Fig. 3) and to open the lower ud of the poi-m, sothat the steam under pressure can again .pass to the upper end of thecylinderE to equalize the pressure on the piston'and to cause the sameto again descend, as previously ex-- plained. The water of cb'ndensationin the 'upper end of the cylinder can readily flow through the branchport binto the port a and from'the latter through the lower end of thecylinder E into the receiving-chamber D and pass with the oil totheobject to be lubricated, as hereinafter more fully explained.

From. the'lower end of the piston F extends 'ashort piston-rod F,'whichsupportsa carrier-valve G, adapted to receive a measured quantity ofoilfrom the receivingchamber D, I

to hold the same in a horelI for the time be-" mg, and to finallydeliver the same to thedelivery-chamber I, openingxinto the. steamchestor, other part to be lubricated and COlli ectedby'the bore II with thereeeiving-cham- {her D.- The carrier valve G consists, essemt jtially,of two valves G" G connected with each other by a stem G formed throughpart of its length with recesses or side chambers G? (see Figs.' 2, 3,and 4) to receive and conj tain a measured quantity of the oil. Thevalves G G are adapted to be seated on'valveseats ll I1 formed at theupper and lower ends of the bore ll the stem G lie n-n' of such -.valveshave to move a distance before the chambers G connect with thereceiving-chainlength that when one valve is seated on its seatthe-other valve is a distance E its seat, as W111 be readily understoodby reference to- F igs. 2 and 3, and the chambers G4 terminate such adistance from the valves G. Githfat the her D or the delivery-chamber I.

When the piston F'is in -a lowermost position, the valve G is onits seatH, and when the piston F is moved upward, as previously 1 explained,then the valve G moves to its seat ber D, so that the oil can pa.

, chambers G to fill the same.

11*, while the valve G moves'oft its seat H,

1 nd the upper ends of the chambers Gr con-' 1 ect with the lower end ofthe receiving-chamfrom the re: ceivingchamber into the sa d valve stemtime'ithe pressure on the piston F has been equali zed,.so that thepistou'descends and carries with it the carrier-valve G, whereby theupper end of the be e-H is closed before the lower end of the said boreis opened into the delivery-chamber I to prevent communication betweenthe delivery-chamber and the above-described operation is repeated-thatis, the oil in the receiving-chamber can pass into the chambers G and bethen transferred to the delivery-chamber I, as abo've explained,

on the nextdownward movement of the pis- :on F. I 1

In constructing the carrier-valve G and the piston F, I prefer to formthe valve G on the lower endyof the piston-rod F, as indicated inFigs-(*2 and 3, and the stem G? is provided at its upper end with a pinG, extending 7 through the piston and its piston-rod, to receive a nutG, abutting against the top oft'he [)lS'iSODy tO fasten the latter andthe carrier-valve together. I do not limit myself to this particularconstruction of the piston and carrier-valve, as it is evident thatthesame' maybe var ed; and I also" do not'li'm it myself to theapplication of the arrangement for the particular purpose mentioned, asthe device may be used for various other purposes.
